A friction element includes interleaved rigid rings 16 and resilient rings 17 bonded together in series, the outer ring 16 being welded to an annular plate 30 connected by fasteners 33 to an annular plate 31 having extensions 34 carrying, on each side, ceramic friction elements. The inner ring 16 is bonded to a hub 11. Each rigid ring has four axial lugs projecting between extensions 24. In use all four resilient rings are stressed to produce a certain spring rate; at a certain torque the lugs of the second ring 16 (counting from hub 11) engage extensions 24 so that the spring rate increases as only three rings 17 are now operative; subsequently as the lugs of successive rings engage the extensions 24, the spring rate increases until at maximum torque only one resilient ring is effective. A friction drag bracket 41 carried by fasteners 33 has a lip 41a frictionally engaging extensions 24 of hub 11 to damp relative movement.

Filed: 1922-12-22
Abstract: 213,325. Graham, H. B., and Read & Campbell, Ltd. Dec. 22, 1922. Direct gas-pressure apparatus, non-automatic. -In apparatus for ejecting liquid from a container in which a cartridge &c. adapted to be pierced to liberate a compressed or liquified gas is housed in a closed chamber so that it is completely cut off from the liquid, the container is in communication with the atmosphere by a vent and on releasing the gas a passage is automatically opened for the gas to pass to the container and the vent is closed. A head 1 screwed into the neck of the container carries a screwed-on cup 8 for the gas cartridge and has a plunger 12 which passes through a collar 11 and has a piston 15 sliding in the lower part of the bore 10. A cap 21 having apertures 22 and attached to the head 1 by bayonet joints 23, holds the plunger 12 and the piston 15 so that normally a passage 14 is closed and at the same time a flattened portion 19 on the plunger registers with the collar 11 to form a passage which communicates with the container through a passage 13 and with the atmosphere through apertures 20, 22. To use the aparatus the cap 23 is removed so that the plunger 12 is forced up by a spring 15; the plunger is them depressed to pierce the gas cartridge by a point 26. On being released the plunger rises to close the passage 13 to open the passage 14 to the container. A flange 27 on the knob 16 acts as a stop on depressing the plunger. A nut portion 5 is provided to take a spanner &c. The adaption of the capsule described in Specification 213,326, [Class 47 (ii), Fireextinguishing, &c.], to the head is described.

Title: Improvements in and relating to The Sintering Of Iron Ores
IPC: C22B1/14
Filed: 1967-07-31
Abstract: 1,153,950. Sintering iron ore. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 31 July, 1967 [7 Sept., 1966], No. 35091/67. Heading C1A. The sintering of iron ore is controlled by continuously monitoring the magnetic permeability. In the event of any change "the degree of oxidation" is determined and if the said proparties lie outside a predetermined zone, the moisture content of the mixture, the amount of return fines or the fuel content are adjusted to bring the conditions back within the said zone. The zone is defined by testing samples having the maximum and minimum acceptable values of cohesion and reducibility to determine the corresponding values of magnetic permeability and degree of oxidation. The magnetic permeability may be measured by placing a sample in the core of a solenoid which forms part of a resonant circuit and measuring the resonant frequency, whilst the degree of oxidation may be simply determined by observing the "gain in blast" or increase in weight on heating in a muffle furnace of a finely crushed sample. In the diagram the rectangle 1234 defines a working zone bounded by the limiting values of gain in blast (g s  g i ) and frequency (f s  fi) determined experimentally to correspond to acceptable properties of cohesion and reducibility in the product.

F., 10, New Court, Lincoln's Inn, London.-(Automatic Sprinkler Co. of America; 910, Standard Bank Building, Cleveland, Ohio, U.S.A.) Dec. 27, 1933, No. 36390. [Class 47 (ii)] In fire-controlling or other apparatus wherein a predetermined rate-of-rise of temperature in a zone causes thermal elements to actuate a release mechanism for a sprinkler valve fire door or other controlled device, a retarding device is included in the release mechanism so that the latter will only be actuated if the rise of temperature persists for a predetermined time. As shown, air bulbs 4 are connected by a tube 7 with vent 11 to a diaphragm chamber 8. The diaphragm 9 is linked to a lever 12 which has a yoke 40 supporting a pawl 42 and a projection 38 engaging a fan 36 forming part of the escapement mechanism 34, 32, 30 of a clockwork 24, 26, 27, 28. The pawl 42 has a tongue 46 adapted to engage the gear wheel 28, and is pivoted to a pivoted arm 18. If heating of a predetermined rate occurs in the fire zone, the diaphragm 9 moves the lever 12 to release the fan 36 and engage the pawl 42 with the gear wheel 28. The clockwork then moves the arm 18 in a clockwise direction, until it moves a lever 50 to release a weight 54. The latter compresses a bellows 60 to release a weight 70 which opens the sprinkler valve 74. If the heating is of short duration, the diaphragm raises the lever 12 to stop the clockwork and disengage the pawl 42, before the arm 18 has been moved far enough to release the weight 54. The arm is then returned to starting position by a spring 22.

[Also in Division B7] Sandwich walls, especially suitable for use as ships' hulls, and consisting of an inner and an outer shell with the intermediate space filled with grains of foamed synthetic resin, are produced by mixing the grains with a binding agent and thereafter forcing them into the intermediate space, for example by means of a worm device. The process is particularly suitable for the production of ships constructed of glass fabric, improving their thermal insulation and resistance to damage and sinking. The shells may alternatively be of other materials, such as aluminium.
